인버터가 개시된다. 본 발명의 일실시예의 인버터는, 인버터의 DC링크 전압의 크기를 조절하는 스케일부, 상기 스케일부의 출력과 인버터 출력전압의 오차를 비례적분(PI) 제어하여 제어신호를 출력하는 PI 제어부, 상기 인버터의 지령주파수와 상기 제어신호를 합산하는 제1연산부, 및 상기 제1연산부의 출력주파수로부터 인버터의 출력전압을 결정하는 전압 결정부를 포함한다.

    The present disclosure relates to an inverter provided in a hoist system, which includes a scale unit configured to control a size of a DC link voltage of the inverter, a proportional-integral (PI) controller configured to perform PI-control on an output of the scale unit and an output voltage of the inverter and outputting a control signal, a first calculating unit configured to sum a command frequency of the inverter and the control signal, and a voltage determining unit configured to determine an output voltage of the inverter from an output frequency of the first calculating unit.
